Title: Liquid developing device
Inventor: KAWAKUBO TOSHIO
IPC: G03G15/10
Filed: 1978-08-24
Abstract: PURPOSE: To achieve not only the reduction in the devloping solution pressure on the surface to be developed and the aversion of fatigue of he developing solution but also the promotion of uniform developing solution supply and stirring action with a simple construction by mutually opposing developing solution discharge parts and letting the solutions being spouted collide against each other.  
     CONSTITUTION: A developing device head 1 which constitutes a developing electrode has the length equal to the width of a photoreceptor 9 and the liquid pool part 2 extending in the lengthwise direction is formed one step lower at the center of the top surface of said head. Multiple developing solution discharge ports 3... are mutually opposedly opened in the right and left side walls of the solution pool part 2. The developing solutions being spouted from the discharge ports 3, 3 collide against themselves in the center of the solution pool part 2 and the greater portions of their acting force are consumed here as stirring action. At the same time, the solutions build up largly upward to the opened part and make contact with the surface of the photoreceptor 9, thereby supplying a large amount of toner particles within the electrophoresis region. On the other hand, the discharge ports 3, 3 are evenly distributed in the lengthwise direction of the developing device head 1 and therefore the electrostatic latent images formed on the surface of the photoreceptor 9 may be developed evenly at high densities.

Title: Sealing apparatus for observation inside tank
Inventor: KAWADA TADAYOSHI
IPC: G02B23/24
Filed: 1988-04-27
Abstract: PURPOSE:To enable observation inside a tank safely even during the operation, by fixing a flange receptacle with a sleeve on a cylindrical body provided with an air supply port and an exhaust port while a sealing body is fitted securely into the body. CONSTITUTION:Both ends of a flexible sleeve 15 are fixed on a flange 9 with a sleeve and a second flange 11 with a sleeve. A spacer 16 is mounted between the flanges 9 and 11 surrounding a sleeve 15 to form a sealing body with the sleeve 15 and the spacer 16 fixed on the flanges 9 and 11. A flange receptacle 6 with a sleeve is fastened on a hollow body 1 provided with a supply port 4 and an exhaust port 5 for air and the sealing body is fitted securely into the body 1. In observation inside the tank, a fiber scope is inserted into the tank through the flange 11 via the flange receiver 6, the flange 9 and a sleeve 15. Then, a pressure air introduced from the supply port 4 acts on the sleeve 15 through a tiny hole of the spacer 16 to contact the fiber scope. This enables prevention of leakage of a pressure or a fluid from the side of the tank.

Title: Disk drive device
Inventor: NAKAYAMA TATSUYUKI
IPC: G11B21/02
Filed: 1998-04-14
Abstract: PROBLEM TO BE SOLVED: To reduce the number of manufactured parts and to reduce the number of mounting man-hours by fixing one end of a guide shaft by pinching it between a chassis and a part-supporting plate and simplifying the mounting to the chassis of the guide shaft. SOLUTION: The inner-periphery side end part of a reference guide shaft 17 is located at an inverse V-shaped space 28 that is formed by a press piece 27 and a reference post 23b being formed at a chassis 13. Then, when the chassis 13 is to be fixed, the reference guide shaft 17 is pinched between a stator substrate 22 and the press piece 27. The inner-periphery side end part of the reference guide shaft 17 is pressed against the reference post 23b and the stator substrate 22 due to the elastic force of the press piece 27 for positioning, and the press piece 27 functions as a pressing means. Since the inner-periphery side end part of the reference guide shaft 17 is pressed against the reference post 23b, it can be accurately positioned to the reference post 23b, thus improving the positioning accuracy for a spindle shaft.

IPC: F02D41/34
Filed: 1978-08-25
Abstract: PURPOSE: To control this device high accurate when an engine revolves at low speeds, by controlling the valve opening time of a fuel injection valve by obtaining the quantity of air sucked per one revolution of the engine from a period of the revolution of the engine and the output of an air flow meter.  
     CONSTITUTION: The output QA of an air flow meter is converted into digital signals by means of an A/D converter 3, read by means of a micro-computer 4 and set to a register 6. A gate circuit 5 is opened only by a period T of the number of revolution of an engine by electric signals from an engine revolution number sensor 2 to let clock pulses from a clock generator 7 pass, and the period T is counted by means of a counter 8. QA and T are multiplied by means of the computer 4, and the valve opening time T p  of a fuel injection valve is put out. Thus, the mixing ratio of air and fuel sucked to the engine of an automobile can excellently be controlled because the valve opening time T p  is proportional to the quantity of air sucked per one revolution of the engine.

Title: Integral extrusion method for plural pereforated pipe
Inventor: SUGIO EIJI
IPC: B21C23/14
Filed: 1988-04-26
Abstract: PURPOSE:To equalize the extrusion speed of each perforated pipe and to constrain the generation of thickness deviation, etc., by extruding plural perforated pipes in a linking state of interposing a link piece. CONSTITUTION:An extrusion material is passed through the upper and lower passing holes 15, 15 of a male die 1, flowed into the forming hole 3 of a die A and extruded by passing through the forming hole 2 and a communication part 24. The flat perforated pipe thus extruded becomes of the body extruded in a linked integral state of the mutual adjacent being interposed by a link piece and becomes actually same as the extrusion of an integral body. The extrusion speed of each perforated pipe can therefore be equalized, so the generation of a thickness deviation, etc., can be prevented. Also, the extruded perforated pile is linked, so the integral handling is enabled and the handling performance and workability are improved.
